Coded continuous wave meteor radar [PDF]

open access: yesAtmospheric Measurement Techniques, 2016
The concept of a coded continuous wave specular meteor radar (SMR) is described. The radar uses a continuously transmitted pseudorandom phase-modulated waveform, which has several advantages compared to conventional pulsed SMRs.

Multi-instrument observations of the Pajala fireball: Origin, characteristics, and atmospheric implications

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Meteor observations provide information about Solar System constituents and their influx onto Earth, their interaction processes in the atmosphere, as well as the neutral dynamics of the upper atmosphere.

Diurnal variation of non-specular meteor trails [PDF]

open access: yesAnnales Geophysicae, 2009
We present results of simulated radar observations of meteor trails in an effort to show how non-specular meteor trails are expected to vary as a function of a number of key atmospheric, ionospheric and meteoroid parameters.

Identifying gravity waves launched by the Hunga Tonga–Hunga Ha′apai volcanic eruption in mesosphere/lower-thermosphere winds derived from CONDOR and the Nordic Meteor Radar Cluster [PDF]

open access: yesAnnales Geophysicae, 2023
The Hunga Tonga–Hunga Ha′apai volcano eruption was a unique event that caused many atmospheric phenomena around the globe. In this study, we investigate the atmospheric gravity waves in the mesosphere/lower-thermosphere (MLT) launched by the volcanic ...

Validation of MIGHTI/ICON Atmospheric Wind Observations over China Region Based on Meteor Radar and Horizontal Wind Model (HWM14)

open access: yesAtmosphere, 2022
The Michelson Interferometer for Global High-resolution Thermospheric Imaging (MIGHTI) on board the ICON satellite provides effective measurement of horizontal winds in the mesosphere and lower thermosphere (MLT) region.

Studying a Long-Lasting Meteor Trail from Stereo Images and Radar Data

open access: yesAtmosphere, 2021
Unique observation of a long-lasting meteor trail of about half an hour duration is described. The trail resulted from a burning meteor from the Leonid storm flux in the middle latitudes over eastern Siberia.

Meteor radar vertical wind observation biases and mathematical debiasing strategies including the 3DVAR+DIV algorithm [PDF]

open access: yesAtmospheric Measurement Techniques, 2022
Meteor radars have become widely used instruments to study atmospheric dynamics, particularly in the 70 to 110 km altitude region. These systems have been proven to provide reliable and continuous measurements of horizontal winds in the mesosphere and ...

Two-dimensional wind field observation based on multistatic meteor radars in central and eastern China

open access: yes地球与行星物理论评
All-sky meteor radars have become a reliable and widely used tool for observing horizontal winds in the mesosphere and lower thermosphere (MLT) region. This provides vital data support for the study of dynamics in this region.

A Comparison of Meteor Radar Observation over China Region with Horizontal Wind Model (HWM14)

open access: yesAtmosphere, 2021
This paper compares the wind fields measured by the meteor radar at Mohe, Beijing, Wuhan, and Sanya stations and horizontal wind model (HWM14) predictions.

Mesospheric radar wind comparisons at high and middle southern latitudes

open access: yesEarth, Planets and Space, 2018
We compare hourly averaged neutral winds derived from two meteor radars operating at 33.2 and 55 MHz to estimate the errors in these measurements.
